DaveK said:The starting spot in the diagrammed shot is "5", and you want to end up at "2" on the third rail, so aim at the "3"rd diamond. 5=3+2. This is the way I've read it in DeadAims post, in Fels book, and many others.
While I don't personally use this system, one of the local players at this pool hall does. He mentioned the system to me, we applied it to this table, and we came to the conclusion that either 5=2+2 or these tables are totally f'ed up.
DaveK said:Rarely is the correct aim for this three rail shot directly at that third diamond.
Correct, but, as I stated in a previous post, it should get you in the ball park under normal circumstances. I don't consider 1.25 diamonds short to even be in the ballpark.
DaveK said:I have found that it is more common to aim at about midway between the 2nd and 3rd diamonds
2 1/4 seems to be pretty popular as the "exactly correct" answer, but, as everyone knows, "exactly correct" is different on each table. 2 1/8 to 2 1/4 is exactly correct on my GCII with well worn 860.
DaveK said:Try the shot starting at each of the foot-rail corners to see if the table is 'square' to itself, often these two shots play a bit differently.
All of the obvious things like that have been tried, and, as stated previously, we're not talking about just one table; this problem persists throughout the pool hall.
